General Description
The Supertex LR8 is a high voltage, low output current, adjustable linear
regulator.
It has a wide operating input voltage range of 12V to 450V.
The output voltage can be adjusted from 1.
20V to 440V provided that the input voltage is at least 10V greater than the output voltage.
The output voltage can be adjusted by means of two external resistors R1 and R2 as shown in the typical application circ...
